25 ton Knuckle boom Truck mounted Crane

F500KC-05 ​​25-Ton Knuckle Boom Truck-Mounted Crane

In confined spaces, the extension range of a telescopic boom crane is often restricted, making lifting operations difficult. Many operators, who frequently work across diverse environments, often struggle to find a single crane that balances lifting capacity with operational flexibility. The F500KC-05 ​​25-ton knuckle boom truck-mounted crane is specifically designed for such conditions; its articulated (knuckle) boom structure allows for flexible folding and unfolding, enabling stable material lifting even in tight areas. This model features a maximum lifting capacity of 25,000 kg, a maximum lifting moment of 62.5 ton-meters, and 360° continuous rotation. With a self-weight of 7,850 kg and a maximum working radius of 14.5 meters, it is widely used in construction, cargo transport, and high-altitude operations. In addition to knuckle boom cranes, we also supply marine-grade equipment—such as ship-mounted telescopic and knuckle boom cranes—as well as specialized machinery like grab cranes and forestry cranes (log loaders) for handling bulk materials or timber.

1. Product Features: The unit features a compact design, requiring only 1,500 mm of mounting space, and is compatible with a wide range of truck chassis. The hydraulic system ensures stable performance, and the unit can be equipped with accessories such as remote controls, personnel baskets, or hydraulic winches to expand its operational capabilities.

2. Tips: Always perform lifting operations in strict accordance with the load chart; never exceed the rated load or working radius. Regularly inspect hydraulic lines and replace hydraulic oil on schedule to minimize system wear.

FAQ

Q1: Can this truck-mounted knuckle boom crane be equipped with a grab bucket?

A1: Yes, a grab bucket assembly can be added, allowing the unit to function as a grab crane—ideal for handling bulk materials like sand, gravel, or scrap. For timber handling, we offer dedicated forestry crane (log loader) configurations.

Q2: Which parts require attention during daily equipment maintenance? A2: Prioritize regular lubrication of all pivot points, inspect hydraulic lines for leaks, and periodically verify system pressure. Hydraulic fluid must be replaced at scheduled intervals to prevent impurities from causing wear to valve assemblies and hydraulic cylinders.

Q3: What after-sales support is available for this model?

A3: The equipment comes with technical drawings, operating instructions, and load charts. A warranty is provided for the main structural components and core hydraulic parts. In the event of a malfunction, remote technical guidance is available, and original manufacturer spare parts can be supplied upon request.

Q4: Can this crane be used directly on a vessel?

A4: This model is a truck-mounted crane and is not suitable for direct use in a marine environment. For offshore lifting operations, we recommend using a ship-mounted telescopic boom crane or a marine knuckle boom crane, equipped with appropriate anti-corrosion features and marine-grade specifications.
